[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-5 The hoisting device for maintaining a gas station motor shown in the figure comprises a column 1, a mounting mechanism is arranged at the bottom of the column 1, the mounting mechanism comprises a mounting plate 2, and a plurality of mounting holes 201 are opened on the side of the top end of the mounting plate 2.

[0023] It should be noted that the mounting plate 2 is a steel plate disc with a diameter of 300 mm and a thickness of 25 mm. At the same time, through the setting of the mounting holes 201, the mounting plate 2 is fixed to the base of the hydraulic lubricating oil station by using M16 bolts passing through these mounting holes 201, so that the entire lifting device can be fixed on the base of the hydraulic lubricating oil station. In the actual setting, the mounting plate 2 can also be directly welded to the oil station base for reinforcement and fixation.

[0024] The top of the column 1 is rotatably connected to a tripod;

[0025] The tripod includes a rotating rod 4, an extension rod 5 is arranged in the middle of the rotating rod 4, a plurality of positioning holes 501 are opened horizontally on the top of the extension rod 5, and the extension rod 5 is fixed to the rotating rod 4 by welding, so that the extension rod 5 serves as a suspension support arm during the setting;

[0026] Specifically, a bearing group 3 for supporting the rotation of the rotating rod 4 is provided between the connection between the column 1 and the rotating rod 4 .

[0027] It should be noted that the bearing group 3 provided in this scheme is composed of three bearings, including two spherical roller bearings and one thrust ball bearing, wherein a spherical roller bearing is installed at the bottom of the connection between the column 1 and the rotating rod 4, and a spherical roller bearing and a thrust ball bearing are installed at the top.

[0028] Among them, the spherical roller bearing is a special type of roller bearing, which has spherical raceways on the inner and outer rings, so that the bearing can freely adjust the inclination during installation, so that it can automatically align when subjected to radial and axial loads. This design makes the spherical roller bearing suitable for applications where there is shaft deviation or axial tilt during installation and operation, and can provide better stability and reliability.

[0029] Thrust ball bearing is a type of bearing specially designed to bear axial load. It usually consists of a spherical raceway, and the friction between the inner ring, outer ring and ball enables it to bear axial load.

[0030] The outer wall sliding sleeve of the extension rod 5 is provided with a lifting ring 7 for mounting a lifting tool, and the top of the lifting ring 7 is provided with a positioning mechanism for cooperating with a plurality of positioning sockets 501 to complete its positioning.

[0031] Specifically, an oblique support rod 6 is fixedly connected between the side of the top of the extension rod 5 away from the rotating rod 4 and the top of the rotating rod 4. The top of the rotating rod 4, the extension rod 5 and the oblique support rod 6 are interconnected to form a triangular structure.

[0032] Specifically, the positioning mechanism includes a positioning rod 8, which is inserted and connected to the ring arm at the top of the ring 7 along the vertical direction. The bottom of the positioning rod 8 passes through the ring arm at the top of the ring 7 and is inserted and connected to one of the positioning holes 501.

[0033] It should be noted that the positioning hole 501 is rectangular in shape, and the positioning rod 8 is a rectangular rod, and the two are adapted to each other. In this way, after the positioning rod 8 is inserted into the positioning hole 501, the lifting ring 7 will not rotate. In this way, after the hand winch is mounted on the lifting ring 7, the hand winch can be used stably.

[0034] Furthermore, limiting grooves are provided on the inner walls on both sides of the insertion point of the lifting ring 7 and the positioning rod 8, and limiting sliders 801 are fixedly connected on both sides of the middle of the positioning rod 8, and multiple limiting sliders 801 are respectively slidably inserted and connected in the limiting grooves.

[0035] Furthermore, a downward pressure spring 9 is provided in the limiting slide groove and at the top end of the limiting slider 801 .

[0036] It should be noted that, in the arrangement of the positioning mechanism of the present invention, if a hand chain hoist is not provided at the lifting ring 7, when adjusting the use position of the lifting ring 7, it is only necessary to directly pull the lifting ring 7 upward, and the lifting ring 7 drives the positioning rod 8 to move out of the positioning insertion hole 501, and the horizontal lateral position of the lifting ring 7 at the extension rod 5 can be adjusted;

[0037] If a hand winch is mounted on the lifting ring 7, the gravity on the lifting ring 7 pulls it close to the extension rod 5. At this time, it is necessary to pull the positioning rod 8 upward. At this time, the positioning rod 8 is forced to move upward and drive the limiting slider 801 to move upward synchronously. At this time, the downward pressure spring 9 is forced to shrink and continue to pull the positioning rod 8. At this time, after the positioning rod 8 moves out of the positioning hole 501, it can slide to adjust the horizontal lateral position of the lifting ring 7 at the extension rod 5, and then release the pull on the positioning rod 8. Under the push of gravity and the downward pressure spring 9, the limiting slider 801 drives the positioning rod 8 to be synchronously inserted down into the positioning hole 501 at the corresponding position.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
